'Be Vit known" that'fI, lowivsov- HAND, a citizen ofthe United States,and a," resident of Orlando, in the county of Orange and State'ofFlorida, have inventeda "certainl new anduseful Improvementinl/Vrenches,

. of what aiefouojwing is a Specification- My present `'inventionrelatesgenerally to wrenches and more particularly'to a Wrench 'Y havingsomething of, Ythenature ofa combination tool,y in that it, is"particularly adaptable to round surfacesjfsuch 'a5 pipg and also topolygonal shaped work. i Theobject of myinvention is to provide a Wrenchwhich vmay be instantly adapted 'to practically any lr-indj ofw'oi'i'ky,`which w'illbe` extremely simple', rspeedyfi'n itskac'tionfand soarranged'that any piece or part may be made or adjustedat any tune.y

Further objects of my invention Willjbek plainly understood from" thefollowing description in which reference is madeto the accompanyingdraivingsforming a part of this specification and in Which-f .n

Figure l is a side elevation illustrating the practical applicationofmywrench to round Worin F ig. 2 is aL longitudinal section therethroughin open yposition,,and L,Fig Buis an edge vieu7 looking toward thelekftkin Fig. 2. f

Referring now toftheseiigures, my improved Wrench includes a handle Ahaving a series of teeth Af at one end, and projecting at one side,whereby to constitutea rigid jaw A2, the handle A having also a slot A3extending therethrough at the inner end of the rigid head A2' formed asdescribed, the' inner portion of Ywhich head, at the sideopposite theteeth A', is provided Witha rearwardly presented edge A4', thus locatedat the forward end of the slotA3 for a purpose to be hereinafterdescribed.r At an intermediate point, and at the inner end of the slotA3, the handle A is provided with a lateral extension A5, having a slotA6 therethrough, and having a grooved outer surface as seen at A7, thegroove forming a seat for i one portion of a U-shaped spring B as most Yplainly seen in Fig. 2.

The movable jaw. C which yis 'provided along its inner surface withteeth C and which is adapted to'opp'ose the rigid jaw A2 at the.outer-end' of the handle A, Vhas a'laterally extending shank C2atxits'inner end,
